To all whom it may concern:

Be it known that I, WILLIAM LOVELL OD- onY, a subject of the King ofGreat Britain,

residing at 1 Beech Hill road, Eltham, in the county of Kent, England,Great Britain,

prevent the too-ra id volatilization of the fumigatingorperumingsubstance and at the same time to expose a large surface ofabsorbent material to the effect of the heat so applied thereto.

I attain my ob ect by the apparatus illustrated by the accompanyingdrawing in which Figure 1 is a vertical section through an apparatusconstructed according to this invention. Fig. 2is an elevation of thesame. Fig. 3 is a cross-section of the same on line X. K. Fig. 1. Fig.4: is an elevation of an electric heater. Fig. 5 is a vertical sectionof a modified form of my invention Fig. 6 is a vertical section showingthe absorbent material with a cavity or reservoir formed in its upperpart. v

Similar letters refer to similar parts throughout the several views.

A is a reservoir of glass or other suitable material containing asuitable liquid or other substance B to be vaporized.

C. is a device of earthenware or other suitable absorbent materialhereinafter referred to as the block 7 adapted to be placed in thereservoir and to be partly immersed in the liquid or other substancecontained therein and partly exposed to the a1r.

' 1 the block has more material at its lower part than at'its upper partand is-hollow.

Surrounding that part of the blockC eX- In the construction as shown byFig.-

b the ring E and projects inside the block so as shown by Fig. 1.

G is a deflector preferably of sheet metal attached to the protectorportion of the apparatus. y w

In the modified form of my invention shown by Fig. 5 the block C hasmore material at its upper part than at its lower part and an electriclamp H or other source of heat is placed inside the block. In such casethe reservoir is formed 'as shown at 1 eain such figure. The said blockin some cases may be provided with la eral perforations and may also insome cases be glazed at its inner-surfaces. A

I is a cover which is provided when the construction is according toFigs. 5 and 6.

It is obvious that what is hereinbefore referred to as the block may bemade of felt or textile fabric, pumice stone or any suitable absorbentmaterial.

When in use the reservoir is charged with the liquid to be vaporized,the block is placed in the reservoir as shown and theelectric heater orother source of heat placed in the block or otherwise applied thereto.As '75 soon as the liquid has risen up the block by capillary attractionthe current is switched on or other heat applied thus causingevaporationat the desired rate to take place, the

vapor being dissipated by the ordinary air so cording to themodification illustrated by Fig. 5 of the drawing Imay form a cavity Jat the upper portion of the block surrounding the hollow therein asshown in Fig. 6 for the reception also of the liquid or other suitablesubstance to be vaporized. It will be obvious that in no case would suchcavity J be lazed. ,c

I claim:

1. In a vaporizer, in combination, a container for the substance to bevaporized, a hollow absorbent block therein adapted to be surrounded bysaid substance, the said lock having a reservoir formed therein, and

a'souroe of heat positioned within the said hollow block.

2. In a vaporizer, in combination, a container adapted to contain thesubstance to be 5 vaporized, a reticulated protector positioned abovesaid container, a hollow absorbent block inclosed within said containerand said protector whereby the lower portion of the block willbesurrounded b the substance and the upper portion 0 the block 1o willbe exposed to the air, and a source of heat positioned within saidhollow block.
